8、I 2009BRITISH STANDARDForewordPublishing informationThis British Standard is published by BSI and came into effect on 30 April 2009. It was prepared by Technical Committee CW/41, Child use and care articles. A list of organizations represented on this committee can be obtained on request to its secr
9、etary.Information about this documentThe committee is aware that sleep bags with sleeves are available but there is limited information available regarding their use and insulation effect. This standard is based on current industry codes of practice which exclude sleep bags with sleeves. As further
10、information becomes available it will be considered by the committee.The committee is considering the development of a test method for assessing the requirements for neck openings.Use of this documentIt has been assumed in the preparation of this British Standard that the execution of its provisions
11、 will be entrusted to appropriately qualified and experienced people, for whose use it has been produced.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.
12、Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct
13、 application.Compliance with a British Standard cannot confer immunity from legal obligations.BRITISH STANDARD BSI 2009 1BS 8510:20091 ScopeThis British Standard specifies requirements for the safety of sleep bags for the use of children with a minimum weight of 4 kg designed to provide sufficient w
14、armth so as to remove the need for additional bedding when sleeping in a cot or similar product in which a child is contained.This standard does not apply to garments with sleeves and feet, i.e. sleep suits or baby gros, or to products designed primarily for outdoor use or to keep children warm when
15、 in a pushchair. It also does not apply to sleeping bags covered by BS EN 13537 and BS EN 13538.NOTE Rationales for the inclusion of some of the requirements given in this standard are given in Annex A.2 Normative referencesThe following referenced documents are indispensable for the application of

22、or feet and legs, designed to contain a child and to provide sufficient warmth so as to remove the need for additional bedding when sleeping in a cot or similar product in which a child is containedNOTE 1 The term “sleep bag” is used to differentiate from “sleeping bags” which are designed for use i
23、n leisure activities. NOTE 2 There may be a filling material enclosed between an outer and an inner fabric. 3.2 thermal resistanceunit equal to ten times the temperature difference between the two faces of a sleep bag (in K) when the heat flow rate across the unit area is equal to 1 W/m2NOTE The the
24、rmal resistance of a sleep bag is also known as its tog value.3.3 tog unit of thermal resistance which is equal to onetenth of a square metre kelvin per watt (m2K/W)NOTE 1 tog = 0.1 m2K/W.3.4 press stud fastenerfastening consisting of male and female component parts, attached to corresponding parts
25、of the sleep bag and fastening together by aligning and applying force3.5 slide fastener fastening consisting of two flexible interlocking stringers, with or without end stops, and a slider so arranged that by moving along the stringers in one direction an opening is formed, and by moving it in the
26、other direction the opening is closedNOTE Slide fasteners are commonly known as zips.4 Test conditions4.1 GeneralUnless otherwise stated, conditioning and testing shall be carried out in the standard atmosphere for testing textiles as defined in BS EN ISO 139.4.2 Tolerances Unless otherwise stated,
27、the following tolerances shall apply: forces: null5% of the nominal force; dimensions: null1.0 mm of the nominal dimension.NOTE Unless otherwise specified, the test forces may be applied by any suitable device which does not adversely affect the results.BRITISH STANDARD BSI 2009 3BS 8510:20094.3 Num

29、imensional stability test in 12.1.5 Apparatus5.1 Thermal resistance measuring apparatus, consistent with BS 53351:1991, D.2 and BS 53352:2006, 4.2 but with the following specific modifications.a) The apparatus shall be horizontal, with the heat flow upwards, designed so that measurements can be made
30、 at the upper hot face of the apparatus and in the ambient air above the quilt.b) The surface of the upper hot face of the apparatus shall be flat, isothermal, and be of a suitable conductive material (see BS EN 31092:1994, 5.1, paragraph 2).c) The central measuring area shall be a square of minimum

Examples of different types of button box are shown in Figure 2a) and Figure 2b). The box shall be of sufficient size to accommodate the attachment to be tested but the shape and
37、dimensions of the box are not critical. The slotted plate shall be as shown in Figure 3 made from gauge plate metal (1.65 null 0.15) mm thick. The slot width, W, shall be such that the attachment being tested can slide onto the plate without damaging the means of attachment (e.g. sewing thread or sh
38、ank).NOTE 1 The slotted plate may be an integral part of the button box, or be interchangeable to allow the testing of attachments of different sizes or types.NOTE 2 Slot widths of (3 null 0.2) mm, (5 null 0.2) mm and (7 null 0.2) mm have been found to be suitable to test the majority of attachments
39、 used on childrens sleep bags.NOTE 3 It is recommended that the button box attachment to the load cell be articulated to make it easier to slide in the component under test.5.5 Press fastener upper grip, for testing of press fasteners, including press stud fasteners, comprising a multipronged claw,
40、with a minimum of three prongs and able to grasp a minimum of 70% of the circumference of the outer rim of the fastener. The prongs shall be evenly spaced. The profile of the claw shall be such that it is capable of gripping the fastener and can be tightened to grip it firmly without causing deforma
41、tion of, or damage to the integrity of, the fastener rim.An example of a suitable grip for the testing of 13, 14 and 15 ligne (8.25 mm, 8.5 mm and 9.5 mm) press stud fasteners is shown in Figure 4.NOTE 1 The three-pronged claw used for tension testing in accordance with BS EN 71-1 should not be used
42、 as this does not have a suitable profile for testing fasteners and could exert a shearing force rather than a direct pull.NOTE 2 Where the outer rim of the male side of the press fastener is not grippable, an alternative grip may be used to grip the centre post.5.6 Press fastener lower grip, for te
43、sting of press fasteners including press stud fasteners, as shown in Figure 5.NOTE The dimensions of this grip have been found to be suitable to test the majority of press fasteners used on childrens sleep bags.5.7 Diamant upper grip, for testing of fused or glued on diamants 3 mm, comprising a two
